In my app, I use Alamofire to fetch data from my server. For each time I fetch, 10 results will be sent from my server to my app. If I only post 3 requests or less at the same time, no any issue. If I post 5 or more requests at the same time, I received below error (1). After about 60s, I received below error (2). I am wondering this is my server issue or ?? Any suggestions? Thanks.
error(1) - 1005
